"lhe object of the invention is to provide improvements in 'Huid mixing devices, and especially in that type ivhichis designed to facilitate the preparation of antiseptic and other fluids for use in douciiiiig the various cavities of the human body, including the oral, nasal, auditory and reproductive organs, the only difference or variation in the use of the device being the use of tubing, nozzles and lo solutions of varying strength and substance.

Another-object is to provide a device for this purposeivliich can be readily attached to and detached from the usual faucet suoli as is found in the batlitubor basin of a pres! room.V l y A further object isto provide a device Which is equally adapted for use in the preparation of a douchefrom either liquids, or froni'soluble solid substances, and in Which device the container for the douche substance is adapted to remain as long as desired in either operative orfinoperative positioinn one case another fluid such as Water mixing with the substance as it passes through the device, and in the other case the Water or carrier fluid passing freely through the device'without having any of the substance addedthereto. i i V y `Still `another object is to provide the combination of a easing haif'ii'igI a removable `closure provided with an aperture, a substance container slidahlysupported Within said apertureand itself having removable closure for its filling port, the sides of said container being( provided with spaced `apertures Which are automatically `closed when :the container isrin inoperative position, and `which aper ture vlie'n said-container is in operative positioiibeing exposed upon theiiiside of 4the casing and adapted toadiiiit a fluid solvent into saidlcontainer, and to permit'the liovv of dissolved substance from'within said con-` tainer intothe interiorof said casing'.

' Anda still further object is t-o provide such a; device as hereinbefoife set forth, comprising the saidcasing and slidably positioned container, With means tomaintain said contaiiiei'in its iiinermc'stforoperative position ivithxrelation tof said' casingland fluid-tight entda lavator laboratorf or oieratin` y yi a l p :n

means so arranged that fluid pressure flowing through said casing iv ill maintain said conengaged.

lVith these and other objects in mind, the present invention comprises further details of construction and operation fully brought out in the following description, when read in conjunction withthe accompanying drawings, in which Fig. 1 is an elevation of one embodiment of the invention; Fig. 2 is a vertical, longitudinal section ofthe saine; 3 is a view showing the parts of thedevice disq assembled and in elevation but in `their normal alignment With the outside casing', a portion ofiWhich is broken away; Fig.' 4 is an elevational View of an attachment for conneet-ing and mixing the hot and cold Water (or other fluid) from orthe like (not shown).

a plurality of faucets -Referringto the drawings, one embodinientofthe invention comprises a preferably cylindrical casing 1, having an inlet opening 2, into Whicliis normally secured a suitable elbow or other shape of tubular iluidsconvey`- ing member 3, the outer which is `preferably tl `free end portion of ared at fl and thence provided ivith an annular recess 5 bounded by an inturne'd flange 6, in said recess there lieing positioned a disc 7, having anaperture 8,

While-a disc 9 of yielding material, such as lrubber or the like, issecured riphery between the disc 7 and the flange 6,

and radially inwardly is aperture 10 adapted to provided with an receive a supply tube or faucet l1 by extending in cylindrical shape through the aperture 8 AThe lower portion 12 erablyconical in shape out-let opening' 13 Vinto in said disc 7.

ofthe casingl l is prefand provided with an which is normally secured an eiidv'of a nozzle or tube connection 14, having a discharge bore 15. The upper portion of said casing is open and provided with an aperture 16 normally connected With vvliati'sA the threaded portion 17 of a plugor cap"18,provided with a circumferentially knurled or notched binding engagementw ofsaid casing.

flange 19, normally in ith the upper free end 1 vinder are provided with spaced perforations 25 at such distanceV from the closure plug 22VV as to permit the use ofthe-lower portion of the interior of said cylinder for the purpose y of measuring any desired liquid, althoughn said container is equally adapted to contain and operatively supp ort particles of solid, yet

soluble, substances, such as antiseptics andV the like, including potassium permanganate.

1 The upper portion of the cylinder 21 is provided with threads 26 adapted to engage correspondingly positioned tlireadsin the upper end Vportion of the aperture-20 in the closure .17,'said cylinder terminating in aradially eX- tending flange27 which jis also knurled or notched as may be desired. The otherwise open upperend portion 28 of said cylinderV is normally closed by means ofa removable plug 29, having an` enlarged bore 3Q, Atermi- Y nating upwardly in an annular flange k31,

there being positioned in said lbore an exter-l nally threaded casing 32 in rotatable connection with.y which is a pin 33, having a flange 34 which is positioned within and is prevented from passing,outwardlybeyoiid,the flange 31.

To the outer end of the pin 33, extending freely beyond the cylindricalclosure 29,-tliere is secured in' any suitableinanner a flexible ele-y ment 35,the'oppositeend of which isremov!v ablyY connected'byuineans of a snap fastener orv the like 36 to an eyelet 37 (securedl at-any, suitable point on the outer lsurface of the VdeviceVk,l e L y lnl the operation of this device, it is to be understood that it may be connected to the' discharge'end vof awater faucet or the like, as

shown in Fig. 2,' orit maybe'connected either l directly orthrough the medium" of a flexible Y that by regulating the flow of suchrelatively `tube with the discharge end 38.v of a T39, :the oppositely extending arms of which are conne'cted by'means 4of 1 3ubing 40 to members 4, sucha's illustrated in Fig. 2, and which arel adapted to beremovably connected to hot and cold water faucets simultaneously 1 in y order hotrand coldwater, the resultingjtemperature ofthe water-passing from' the T 39 into the casing lwill be at :the temperaturedesired.

lt is also to be understoodthat a tubular connection of any vdesired length, size, or ma'-V teri al may beconnected to the dischargeicon nection o r nozzle 11i of the device andinturn Vmay be vprovidedwith any suitable type of nozzle depending upon the purpose for which the device is being used.y

. 1 :Having these vfacts mind, `either'soylid orv vliquid antiseptic', disinfectant, Orfother substance (not indicated) is placed within the lower portion of the container 21 after releas ing its threaded connection 26, raisingrit, and removing the plug 29. With said cylinder made of bakelite or similar semi-transparent material, the quantityV of the particular substance' within said cylinder can be measured with accuracy Vandy in this position it will be noted-thatthe perforations 25 are not only removed from exposure to the interior of the casing-f1, buta'r'e 'positioned,'in fact, above the closure 18. Afterplacingfthe desired'sub-` stance within said cylinder, the plug 29 is replaced as showninFigs. 1 and 2 and the cylinder lowered into the operativeY position also shown. Dissolving liquid such as water passingthrough the inlet 2 passes to a certain degree through the perforations 2,5 andv there mixes with, dilutes, or dissolves, la portion of thesubstance above referred tovand thence carries; sucht vportion outwardly .through others of said perforations into 'the casing l',

thence through the outlet 13.1and any tube or nozzle connected thereto. l a Y l When the cylinder 21 is in the operative ypo-V sition shown in Fig. 2, it is, as before stated,

necessary in suchA position to secure it by its being forced outwardly therefrom by. fluid pressure entering throughv the inlet 2. When it is desired that water or similar fluid from the faucet or the like 11 shouldpass throug the device and any nozzle 'connected therewith, the threads 26 are released andthe fluidi pressure entering the VVinlet, 2 autc'matically` forces the cylinderl2l upwardly and mainmeans of the threads '26 .,inforder toV preventv tainisptlie same in such-,upper positionwith the closureflange 23 compressing the gasket-34v firmly against the under..l `surfacerof the casing closure 18, afterwhichthe iluidlpasses throughsaid casing without taking; with it any portion of such substance as maybe with- Y Y Yin the'vupzwardly extending/cylinder; `and flows freely through and fromthe-outlet'13. i l,
